The role of habitat simplification and seasonality in shaping interactions between ants, plants and herbivores in a neotropical savanna

open access: yesEcological Entomology, Volume 51, Issue 2, Page 381-394, April 2026.
We evaluated how chronic anthropogenic disturbances (CAD) and seasonal variation influence interactions between ants and plants with extrafloral nectaries (EFN's), with emphasis on the responses of ants, herbivores, and plants. Ant and herbivore diversity remained stable across seasons in the preserved cerrado, whereas the pasture had higher ant ...

Structure of floral nectaries, nectar production and sugar composition in nectar of 7 species of Vicia L. Fabaceae

open access: yesActa Agrobotanica, 2013
Nectaries of investigated species of Vicia were ranked into 3 morphological types: automorphic (V. sepium L.), transitoric (V. angustifolia L., V. sativa L., V. villosa Roth, V. cracca L.) and flat, epimorphic (V. hirsuta (L.) S. F.

Origin and ontogeny of the extrafloral nectaries associated to the inflorescences of Vigna candida and Vigna caracalla (Leguminosae, Phaseoleae) [PDF]

open access: yes, 2015
The morphology , ontogeny and secretion of the extrafloral nectaries (EFNs) in the inflorescences of Vigna candida and Vigna caracalla were studied. The node s along the inflorescences were processed with standard techniques for light as well as scanning

Neglected Floral Visitors in the Galapagos Islands: Understanding the Structure of Ant‐Flower Interaction Networks

open access: yesJournal of Applied Entomology, Volume 150, Issue 3, Page 321-332, April 2026.
ABSTRACT Ant‐flower interactions are prevalent in many ecosystems, yet their ecological significance remains poorly understood, particularly in isolated systems like the Galapagos Islands, where unique biotic assemblages create distinct interaction networks.

Transcriptomic and microstructural analyses in Liriodendron tulipifera Linn. reveal candidate genes involved in nectary development and nectar secretion

open access: yesBMC Plant Biology, 2019
Background Nectar is a major floral attractant and reward for insects that ensures pollination. Liriodendron, a genus of the Magnoliaceae family, includes only two relict species, L. chinense and L.

Structure of trichomatous nectaries in flowers of Lonicera kamtschatica (Sevast.) Pojark.

open access: yesActa Agrobotanica, 2012
The structure of the floral nectaries of Lonicera kamtschatica was examined using light microscopy, scanning electron microscopy and transmission electron microscopy. Nectariferous tissues are located in the lower portion of the corolla tube.
